This is the adjusting screw that is used to push the bottom rubbers up against the rocker arm centres. These need regular adjustment to prevent oil leaking from the cambox - Manufactured as per the original items, with square adjusting heads - Made in a high grade stainless steel, these are too pretty to sit under the cambox!

This is the original 'standard length' item (copied from an original pre-war item), but we also offer a slightly longer length item (0064c), which can be used if you wish to use less rubber but apply more pressure - if you have a worn rocker casting, more prone to leacking.

Overall length of this item: 39.8 mm

We also supply the correct 'reduced head' nuts, as originally fitted, also made in stainless steel (Item No. 0064b).
